Move the decimal twice to the right to get a decimal (it should start behind the 2 and end up in front of the 7)
For a fraction just put it over 100 72/100
2 is greater then -5.
2 is a positive number unlike -5 it is a negative which is less then 2.
Answer:
2.5cm^2
Step-by-step explanation:
so diameter is basically radius*2...to find radius(since area of circle is pi*r^2 we need to divide diameter by 2)
so 1.8/2=0.9
now,
pi*0.9^2
pi*0.81
2.5 cm^2
you'd use the pythagorean theorem.
a^2+b^2=c^2
a is the first leg, b is the second leg, and c is the third leg.
10^2+13^2=c^2
100+169=c^2
269=c^2
take the square root of both sides
16.4=c
16.4cm is your answer!
2/12 is the correct answer
